SPECIFICATION fqrmmg part of Letters Patent No. 226,103, dated `Marel; so, 1880.

l Application filed January 2 9, 1s80. Y

To all whom 'it may con-cern Be it known that we, ALvIN D. Puntuar:v

and LUTHER BUFFER, both of Boston, in the county of Suffolk andState of'Massachusetts, h ave invented certain Improvements in Soda-Fountains, of -which the following is av specification. s

This invention relates to fountains for soda and other aerated waters or liquids in which a nonfcorrosivelining is employed coveredy l two substantially iuthe manner and Vbythe "means hereinafter described, whereby' I 'obi' tain great strength of parts and entirelyprevent leakage of the contents ofthe receiver.

The drawings accompanying this specification represent, in Figures l and 2, vertical s'ections of a receiver containing our invention.

In said drawings, the lining A of the re-- ceiver, which is usually made of block-tin, is shown as composed of three portions-viz., a semi-globular bottom, a, and crown or top b, and a straight cylinder, c, which constitutes the body. The joint between the crown b and body c .'Inay beof any suitable character, in

the presentinstance being a scarfedand lapped and soldered one, and said crown b has a central orifice, d, to -permit of escape of the contents of the receiver. V

The outer shell, B, of the receiver is composed of sheet-steel or other'metal, and emthe nozzle serving as a means of connection, v

braces a straight cylinder or body, C, and a semi-globular head orcap, D, the perimeter of the latter overlapping the former,'and'the two securely riveted or soldered together, or both riveted and soldered. The, cap D of the s'hell O also has a central orifice, e, of somewhereby the receiver is charged with or emptied of its contents. The bottom of the receiver is constructed as follows: Thev semi-globular bottom a of the lining and the lower cap or bottom piece, h, of the outer shell are placed together and the periphery' of the former turned over the edge of the latter, as shown at i in the drawings, the diameter of the whole being such as to v tightly fitthe lower end ofthe interior of the lining A, into whichfit is inserted, as shown at j.

Thev lower end of the shell or cylinder() extends below the lower end of the lining-cyl- Yinder c, andfwith the bottom cap, h, providesv an annular recess, k, which is filled with a mass of solder, which serves toA securely-conline the bottom to the outer casing, C.

The base or support of the receiver is shown at Ev as.a cylindrical one, having an interior ann ular flange, l, to bear against the under side of the bottom h of the receiver, or against such bottom and the mass of solder contained iu the 1 recess k, the said ilange servingto strengthen and support the bottom of the receiver and d,

being soldered tovsuch bottom.

A short cylinder, F, incloses and is soldered to the lower part of the cylinder C, and so as parts a small quantity of solder may be run into the channel m. o

By theA above construction of fountain we prevent possibility of leakage from vthe interior of the receiver, and we obtain great strength and stiffness of the parts.

A modification of our fountain is shown`inv Fig. 2 of the drawings; In this insta-nce the outer casin g or shell, C, is continued entire to the bottom of the fountain, and preferably abuts against an annular ledge, n, formedupon v lower end of said shell, shall be caused. to ow floated throughout the entire joint.

e l eearca possible, to introduce the solder to the central provide a very strong joint.

part of the joint, but only a certain distance from each side. By employing the holes` as statedthe solderis admitted andledthroughout the entire lap. We also do the same with the annular base E after it is in place within the lower end of the case C-that is, we create a series of holes, ro', &c., in the lower part of such base, which admit solder between it and the case, and which, in conjunction with rivets,

We claim-as our invention, and desire t0 secure by Letters Patent of the United States, as follows:

l. The bottom of the receiver, composed of the inner semi-spherical head ordisk, a., and the outer cap, h, with the periphery of the former turned or lapped over the edge of the latter, and the whole inserted withiuthe lower end ofthe lining of the cylinder, substantially. as and for purposes stated.4

2. The combination, with the lining-cylinder c and bottom piece, anof the outer shell or cylinder, C, extending below the lining-cylinder, substantially as described, whereby an annular solder-receiving recess, k, between said parts is provided. i

3. In combination, the case 0,1iniug A, bottom plate, h, and base E, with its ange l, substantially as and for purposes stated.

4. The crown or upper head of the receiver, composed of the interior semi-spherical cap or disk, b, and outer cap, D, the inner edge of the former overlapping the -adjacentedge of the latter, and the outer periphery of the said cap D overlapping and being riveted to the cylinder C, substantially as described.

5. The combination of the inner and outer caps or disks, b and D, andthe nozzle D', as

herein shown and explained, the lower end of i the nozzle abutting against thelapped edge of the cap b, which is intermediate between such nozzle and the outer cap,D,'and a mass of solder being runabout the joint between the outer lower edge of the nozzle and the top of.

said cap D, substantially as and for purposes stated.
